Hook up 2 lights one switch

Three-way switches require a three-wire cable: The cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches. The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing. Two terminals will be on one side of the switch housing; one terminal on the other side. Four-way switches have four terminals.

Multiway switching

Now in the diagram above, The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc.. The white wires are wire nutted together so they can continue the circuit.

Now as for the ground wire. It is very important to connect the ground wire to the switch as well. The Green screw on the 2-way switch is for the ground so all ground wires should be connected as seen below. All ground wires bare copper are all now connected incoming ground, load ground and switch ground. This makes for a safe protected circuit by having all grounds intact. So what have we accomplished. By wiring a 2-way switch, The circuit below shows the basic concept of electricity flow to the load.

Let's assume the load you are controlling is a light. The electricity flows from the hot wire black through the 2-way switch shown in off position and then to the light and returns through the neutral wire white. This is a completed circuit. Now by understanding the diagram above, go up to the top diagram and by using the concept shown here, just use your mouse pointer on that diagram and follow the flow from black wire hot wire to the load and return through the white wire neutral.

This should give you a good basic understanding how the 2-way switch circuit works and will help you in adding or changing a 2-way switch. So now that you have a basic concept of wiring a 2-way switch, let's look at the following 2-way switch diagrams to see which type of circuit scenario you have. After you have pulled your switch out from the wall, the wires in the box and connecting to the switch should look like one of the following. Wiring a 2-Way Switch How to wire a 2 way switch.

Wiring a 2-way switch is about as simple as it gets when it comes to basic house wiring. First of all we need to go over a little terminology so you know exactly what is being discussed. Go to my Switch Terminology Page where I discuss the terms used for the different types of home electrical switches. It should also help in understanding the functions of each type of switch.

Now a typical circuit will contain a 3-wire cable known as romex. The cable consist of a black wire, a white wire and a bare copper wire. This simple diagram below will give you a better understanding of what this circuit is accomplishing.

You connect the 2 white wires together, and then connect the other so if one light blows, the current can still continue to the other lights to. Run a #14 -2 wire from the sub panel box to a device box for a plug to run a light switch to only one light I would connect the black wire from.

Three way switches have become very popular because it adds convenience and ease to lighting in large rooms, hallways and staircases. For more flexibility, add a four way switch. Take your time, mark the wires properly and you will not only be successful, you will stay sane. The first thing you will need to determine is where the power is coming from and where the switches are positioned. In this first example, the power is coming in to the first switch, flowing along to the second switch and ends at the light.

In this tutorial, we will show you how to make 2-way switching connection.

A double-switch allows you to operate two lights or appliances from the same location. Double switches, sometimes called "double pole," allow you to separately control the power being sent to multiple places from the same switch.

Three-Way and Four-Way Switches--How They Work

You'll often see us refer to 2-wire and 3-wire lighting systems. This is an important point as many products, such as relays, cannot work if installed into a 2-wire system. This application note explains the difference between 2-wire and 3-wire lighting systems and helps you understand which version you have in your installation. Firstly, what do we mean by 2-wire and 3-wire systems. The simple explanation is that a 2-wire system does not include a Neutral wire at the light switch, the 3-wire system does include the Neutral at the switch.

I am remodeling my basement, currently I have 5 light fixtures and each one has its own switch. I would like to make it so when I turn on the switch at the bottom of the stairs all the lights turn on. I would also like to add several more light fixtures. I am new to electrical work. I have a solid background with framing and drywall. The basement is not finished so I have great access to all ceiling joints and current fixtures. I have been reading online about 2 wire nm. I am curious though how you run wire to one fixture, hook it up, and then run the wire to the next fixture. Basically, you want to start with a switch.

The common household circuits used in electrical wiring installation are and should be in parallel. Mostly, switches, Outlet receptacles and light points etc are connected in parallel to maintain the power supply to other electrical devices and appliances through hot and neutral wire in case if one of them gets fail.

Installing A 3-way Switch With Wiring Diagrams

While a three-way switch is very simple to many who visit Instructables. Understanding how the circuit works satisfies curiosity. It can also help to diagnose a three-way switch that does not work because someone wired the circuit incorrectly. This is the basic circuit for a three-way switch. The gray circle represents a light bulb controlled by the two switches. It is gray because it is "off. The green rectangles represent the switches.

If there are lights in your house that can be controlled from two different light switches as opposed to just one , then the light is commonly referred to as a three-way light, and the switches are referred to as three-way light switches. But once you add in a second switch to control the same object, things can get a bit complicated. These are called single-pole light switches, and they can turn on or off a light fixture from a single location. These are the most common types of light switches and are mostly found in bedrooms, bathrooms, and other simple room layouts where you would really only need one light switch. In a traditional wiring setup with a single light fixture and a single switch, you have a hot wire coming in from the electrical panel that supplies the power to the light fixture. However, a light switch is installed in line with that hot wire.

Here's how to swap outdated three-way light switches for something much better. Don't put up with old three-way light switches like this. Swap them out for something new and improved. Archaic light switches might as well be from the stone age. All they do is turn a light on and off. They can't dim lighting gently or remember the brightness level you prefer. Outdated switches don't play nicely with LED bulbs either.

Now in the diagram above, The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc.. The white wires are wire nutted together so they can continue the circuit. Now as for the ground wire.

In building wiring , multiway switching is the interconnection of two or more electrical switches to control an electrical load often, but not always, lighting from more than one location. For example, this allows lighting in a hallway, stairwell or large room to be controlled from multiple locations. While a "normal" light switch needs to be only a single pole, single throw SPST switch, multiway switching requires the use of switches that have one or more additional contacts and two or more wires must be run between the switches. When the load is controlled from only two points, single pole, double throw SPDT switches are used. Double pole, double throw DPDT switches allow control from three or more locations. In alternative designs, low-voltage relay or electronic controls can be used to switch electrical loads, sometimes without the extra power wires.
